ping20Si is the world's smallest, lightest, most affordable Mode S ADS-B transponder. At just 20 grams, it allows drone aircraft to respond to Mode S radar interrogations by ATC and TCAS. ping20Si also transmits ADS-B on 1090MHz. No deviations from the Minimum Performance Standards of DO-181E and DO-260B at 20W nominal output power. GPS and pressure altitude data are provided by the onboard FYXnav position source and integrated barometer. No autopilot integration is required. Simply apply power and program via the ping wireless application. If autopilot integration is preferred, ping20Si is compatible with many popular autopilots.

Dialysis pillow
Size: Medium, Color: Grey
I got it from my husband when he’s taking Dialysis. I like that it doesn’t slide down the chair in his recliner. It makes it more comfortable for my husband while he’s doing dialysis.

Comfy
Size: Medium, Color: Grey
Love it, has Velcro so doesn’t shift and when I took it out of vacuum bag thought it wouldn’t be good but after 24 hours puffed up and feels like soft memory foam. Perfect for a chair I have with a lower back. A big thumbs up January 25, 2025: I change this to a 4 star, after using there are white silk like strings coming off the material onto my hair. Not sure why!!!!!!!!

Wish The Adhesive Pad Worked With Leather
Size: Medium, Color: Grey
The pillow is comfortable but the adhesive pad on it needed to be more sticky for leather. I still give five stars because they reached out and offered to help with a full refund, and asked for pictures to help identify the problem.

Made a great pillow better.
Had an awesome pillow but if I didn't fluff it before going to sleep my neck would hurt the next morning. Ordered this and put about 70% into a cardboard box to expand then shoved it into my pillow. Its been great 👍 put the rest in another pillow. Had no scent. My pillows are king sized.
